A microscope image of a beat-up-looking sample that was abandoned in one of our storage boxes. It looks like maybe it used to have some kind of coating on it, which has deteriorated, or maybe the coating never came out well in the first place, which would be why it was abandoned. I looked at it under the microscope out of idle curiosity, having a couple of minutes to kill while the etching machine worked on one of my other samples. This cool starscape is what I was treated to - I inverted the colors afterwards for added drama.
